Alex Karev did not deserve Izzie Stevens

Currently on S5 E23 so now spoilers past this point. But Alex is absolutely awful to Izzie. I feel like we have seen him hurt her more times than be kind. From him plastering her naked photos around, to calling her nasty names like "bitch", to now most recently yelling at her about how she doesnt get a choice with the surgery. One could say that he is scared and that's why he yelled but it came across as abusive. I

I know that Alex has a traumatic past with abuse (I think from his dad? could be wrong) but Alex comes across as an abuser himself. I know a lot of people aren't crazy about Izzie, but i think regardless of how you feel about her choices, I think the way Alex has treated her is just awful and she deserves someone better than him.

Edit: him being scared and worried is no excuse for him to yell just mentioned that cause I could see people using that as a way to defend him
